General Description
The AO4914 uses advanced trench technology to provide
excellent R DS(ON) and low gate charge. The two
MOSFETs make a compact and efficient switch and
synchronous rectifier combination for use in DC-DC
converters. A Schottky diode is co-packaged in parallel
with the synchronous MOSFET to boost efficiency further
AO4914 is Pb-free (meets ROHS & Sony 259
specifications). AO4914L is a Green Product ordering
option. AO4914 and AO4914L are electrically identical.
